the sex energy transforms the more you spiritually advance, you might find for whatever reason that you no longer need a different body to express yourself properly.
you might then regret getting a sex change, you might not even let it bother you, its all about what YOU want.
but also consider the problems of having your male genitals removed when it comes to yoga and meditation, your not stupid im sure and you know what comes after hormone treatments, that is sex reassignment if you ever want it.
just know your spiritual advancement will be brought to a screeching halt for several months to a year if you decide to fully change your sex.
i dont know if you will ever be internally strong enough for yoga, or raising the kundalini energies...but it is something to consider "can you handle the kundalini serpent in a feminized body?"
also understand that with a more powerful soul, more powerful biokinesis is possible.
